Behaviour of glasses under high pressure

In passing we may note that there is a converse behaviour exhibited by some tetrahedral crystalline solids (Sikka, 1991). This is the reversible pressure amorphisation. Examples are provided by crystalline SnLt, Si02 and several others, all having tetrahedral structural units in the structure. Tetrahedral units do not fill space and the pressure is likely to force the extra volume out resulting in amorphous structure which reverts to the crystalline phase once the pressure is removed.
